轿车传动系总体方案设计及万向传动轴的设计 汽车设计课程设计 题 目 轿车传动系统总体方案及万向传动轴的设计 院 （系） 机械与汽车工程学院 专 业 车辆工程（新能源） 年 级 2021级 学生姓名 学 号 指导教师 1 摘要 汽车传动系统的基本功用是将发动机发出的动力传给驱动车轮。组成 现代汽车普遍采用的是活塞式内燃机，与之相配用的传动系统大多数是采用机械式或液力机械式的。普通双轴货车或部分轿车的发动机纵向布置在汽车的前部，并且以后轮为驱动轮，其传动系统的组成和布置发动机发出的动力依次经过离合器、变速器(或自动变速器)和由万向节与传动轴组成的万向传动装置，以及安装在驱动桥中的主减速器、差速器和半轴，最后传到驱动车轮。传动系统的首要任务是与发动机协同工作，以保证汽车能在不同使用条件下正常行 驶，并 具有良好的动力性和燃油经济性。 关键词：离合器、变速器、万向节传动轴、 驱动桥、主减速器、 差速器、 半轴、驱动车轮 word文档 可自由复制编辑 Abstract The basic issue of Automotive driveline is to driving force from the engine to drive wheels. The modern Motor commonly used is the piston-type internal combustion engine and usually use mechanical drive system or hydraulic mechanical drive system to match with it. The engine of General biaxial goods or part of the vertical layout are in the front of the car, and use the rear wheel for driving wheel, the composition of the drive system and arrangement of the engine power to issue the order after clutch、gearbox (or automatic transmission) and the drive shaft gear which make up of the universal section and the composition, and the main reducer which installed on the drive axle 、 differential and axle, and finally is the drive wheels.The primary tasks of transmission is to work together with the engine for ensure that the use of motor vehicles to normal in different traffic conditions, and has good power and fuel economy. Key words: Clutch, transmission, drive shaft universal joints, drive axle, main reducer, differential, axle, drive wheels 3 目 录 任务书 .............................................................................................................................................. 5 第1章 概述 ..................................................................................................................................... 6 第2章
